Note The air filters are single-use only. They must not be cleaned and reused. This is a Telcordia NEBS requirement, GR-63-CORE Issue 4.
Note Air filters must be inspected every month. If they are dirty or clogged with dust, they must be replaced with a new air filter.
Note If you install the air filter below 15454E-CC-FTA or 15454-CC-FTA, only filters with part numbers 700-23193-01 and 700-23194-01 can be used in this configuration.
Caution Although the air filter can work with older fan trays if it is installed with either side facing up, it is recommended that you install it with the metal bracing facing up to preserve the surface of the filter. You must install the air filter with the metal bracing facing up with 15454E-CC-FTA or 15454-CC-FTA.
Note To install the air filter inside the air ramp unit (15454E-AIR-RAMP or 15454-AIR-RAMP), use the ETSI version of the air filter (15454-FTF2 or 15454E-FTF4).
Step 1 If the air filter is installed in the external filter brackets, slide the filter out of the brackets while being careful not to dislodge any dust that might have collected on the filter and proceed to Step 8. Figure 6-1 shows the fan-tray air filter in an external filter bracket on an ANSI shelf. Figure 6-2 shows the fan-tray air filter in an external filter bracket on an ETSI shelf.
Step 2 If the filter is installed below the fan tray and not in the external filter brackets, open the front door of the shelf assembly. If the front door is already open, proceed to Step 3.
a. Open the front door lock.
The ONS 15454 comes with a pinned hex key for locking and unlocking the front door. Turn the key counterclockwise to unlock the door and clockwise to lock it.
b. Press the door button to release the latch.
c. Swing the door open.
Step 3 (Optional) Remove the front door using the "DLP-G10 Remove the Front Door" procedure". If you do not want to remove the door or it is already removed, proceed to Step 4.

NTP-G116 Replace the Fan-Tray Assembly of the ONS 15454 Shelf Assembly
Caution The 15454-FTA3 fan-tray assembly can only be installed in ONS 15454 R3.1 and later shelf assemblies (15454-SA-ANSI, P/N: 800-19857; 15454-SA-HD, P/N: 800-24848). The fan-tray assembly includes a pin that prevents it from being installed in ONS 15454 shelf assemblies released before ONS 15454 R3.1 (15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1, P/N: 800-07149). Equipment damage can result from attempting to install the 15454-FTA3 in a incompatible shelf assembly.
Caution Do not force a fan-tray assembly into place. Doing so can damage the connectors on the fan tray and/or the connectors on the backplane.
Caution 15454-CC-FTA (ANSI) is compatible with Software R2.2.2 and greater, and shelf assemblies 15454-SA-ANSI and 15454-SA-HD. 15454E-CC-FTA (ETSI) is compatible with Software R4.0 and greater, and shelf assembly 15454-SA-ETSI.
Caution As with the FTA3, the 15454E-CC-FTA and 15454-CC-FTA Fan Fail LED on the front of the fan-tray assembly illuminates when one or more fans fail to indicate that a fan-tray assembly or AIP replacement is required. But the Fan Fail LED on the 15454E-CC-FTA and 15454-CC-FTA will also illuminate when only one power source is connected to the chassis, and or any fuse blows. In such conditions, the Fan Alarm is triggered and the fans run at maximum speed.
Note To replace the fan-tray assembly, it is not necessary to move any of the cable management facilities.
Step 1 Review Table 6-1 (ANSI) or Table 6-2 (ETSI) to ensure that you have compatible components when replacing the fan-tray assembly. Note the alarms that will be generated when an incompatibility occurs.
Note If you need to determine the hardware that has been installed on a node, click the Inventory tab in node view.

If you do not need to upgrade software or have completed the software upgrade, proceed to Step 3.
Step 3 Record the MAC address of the old AIP:
a. Log into the node where you will replace the AIP. See the "DLP-G46 Log into CTC" task.
b. In node view (single-shelf mode) or multishelf view (multishelf mode), click the Provisioning > Network tabs.
c. Record the MAC address shown in the General tab.
Step 4 Call Cisco TAC for assistance in replacing the AIP and maintaining the original MAC address. See the "Obtaining Documentation, Obtaining Support, and Security Guidelines" section.
Step 5 Complete the "DLP-G13 Remove the Lower Backplane Cover" in the Cisco ONS 15454 Hardware Installation Guide.
Step 6 Unscrew the two screws that hold the AIP cover in place.
Step 7 Grip the cover and gently pull away from the backplane.
Note On the 15454-SA-HD (P/N: 800-24848), 15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1 (P/N: 800-07149) shelves, the AIP cover is clear plastic. On the 15454-SA-ANSI shelf (P/N: 800-19857), the AIP cover is metal.
Step 8 Grip the AIP and gently pull it away from the backplane.
Step 9 Disconnect the fan-tray assembly power cable from the AIP.
Step 10 Set the old AIP aside for return to Cisco.
Caution The type of shelf that the AIP resides in determines the version of AIP that should replace the failed AIP. The 15454-SA-ANSI shelf (P/N: 800-19857) and 15454-SA-HD (P/N: 800-24848) currently use the 5A AIP, (P/N: 73-7665-01). The 15454-SA-NEBS3E, 15454-SA-NEBS3, and 15454-SA-R1 (P/N: 800-07149) shelves and earlier use the 2A AIP (P/N: 73-5262-01).
Caution Do not put a 2A AIP (P/N: 73-5262-01) into a 15454-SA-ANSI (P/N: 800-19857) or 15454-SA-HD (P/N: 800-24848) shelf; doing so will cause a blown fuse on the AIP.
Step 11 Attach the fan-tray assembly power cable to the new AIP.
Step 12 Place the new AIP on the backplane by plugging the panel into the backplane using the DIN connector.
Step 13 Replace the AIP cover over the AIP and secure the cover with the two screws.
Step 14 Replace the lower backplane cover and secure the cover with the five screws.
Step 15 In node view (single-shelf mode) or multishelf view (multishelf mode), click the Provisioning > Network tabs.
Caution Cisco recommends that TCC2/TCC2P/TCC3/TNC/TSC card resets be performed in a maintenance window to avoid any potential service disruptions.
Step 16 Reset the standby TCC2/TCC2P/TCC3/TNC/TSC card:
a. Right-click the standby TCC2/TCC2P/TCC3/TNC/TSC card and choose Reset Card.
b. Click Yes in the Resetting Card dialog box. As the card resets, a loading (Ldg) indication appears on the card in CTC.
Note The reset takes approximately five minutes. Do not perform any other steps until the reset is complete.
Step 17 Complete the "DLP-G250 Reset the TCC2/TCC2P/TCC3/TNC/TSC Card" task in the Cisco ONS 15454 DWDM Configuration Guide to reset the active TCC2/TCC2P/TCC3/TNC/TSC card.
Step 18 From the File drop-down list, choose Exit to exit the CTC session.
Step 19 Log back into the node. In the Login dialog box, choose (None) from the Additional Nodes drop-down list.
Step 20 Record the new MAC address:
a. In node view (single-shelf mode) or multishelf view (multishelf mode), click the Provisioning > Network tabs.
b. Record the MAC address shown in the General tab.
Step 21 In node view (single-shelf mode) or multishelf view (multishelf mode), click the Circuits tab. Note that all circuits listed have a status of PARTIAL.
Step 22 In node view (single-shelf mode) or multishelf view (multishelf mode), choose Repair Circuits from the Tools drop-down list. The Circuit Repair dialog box appears.
Step 23 Read the instructions in the Circuit Repair dialog box. If all the steps in the dialog box have been completed, click Next. Ensure that you have the old and new MAC addresses.
Step 24 The Node MAC Addresses dialog box appears:
a. From the Node drop-down list, choose the name of the node where you replaced the AIP.
b. In the Old MAC Address field, enter the old MAC address that was recorded in Step 3.
c. Click Next.
Step 25 The Repair Circuits dialog box appears. Read the information in the dialog box and click Finish.
Note The CTC session freezes until all circuits are repaired. Circuit repair can take up to five minutes or more depending on the number of circuits provisioned.
When the circuit repair is complete, the Circuits Repaired dialog box appears.
Step 26 Click OK.
Step 27 In node view of the new node, click the Circuits tab. Check to ensure that all circuits listed have a status of DISCOVERED. If all circuits listed are not DISCOVERED, call the Cisco TAC at (800) 553-2447 to open a Return Material Authorization (RMA).
Stop. You have completed this procedure.
